German Spring Power Cord

German spring power cord Features

 

Finished product outer diameter: varies due to different wire core specifications and sheath thickness. For example, the finished product outer diameter of a 2-core 0.75mm² H03V VH2-F power cord is about 5.4mm; the finished product outer diameter of a 3-core 0.75mm² H05V VH2-F power cord is about 6.5mm.
Temperature parameters: The normal operating temperature range is generally -10℃～80℃, and it can maintain stable performance within a certain temperature range.
Certification parameters: Certified by VDE (German Electrical Engineers Association), ENEC (European Committee for Standardization), etc.

What are the benefits of using oxygen-free copper as the core material of the spring power cord?

High conductivity: Oxygen-free copper has extremely high purity and extremely low impurity content, which makes it have excellent conductivity. When transmitting the same amount of electricity, the oxygen-free copper core can effectively reduce resistance, reduce the loss of electricity during transmission, and improve the transmission efficiency of electricity. This not only saves energy, but also reduces the operating cost of the equipment. For some equipment that requires high power supply stability, such as medical equipment, industrial automation equipment, etc., the spring power cord with oxygen-free copper core can ensure a stable power supply and reduce voltage fluctuations and power outages caused by excessive resistance.

Good flexibility: Oxygen-free copper has good ductility and flexibility, which makes the spring power cord less likely to break when it is frequently stretched, bent and twisted. For equipment that needs to be moved or adjusted frequently, such as power tools, stage equipment, etc., the spring power cord with oxygen-free copper core can adapt to various complex usage scenarios, extend the service life of the power cord, and reduce the risk of failure caused by core breakage.

Strong anti-oxidation property: The oxygen content in oxygen-free copper is extremely low, and it is not easy to react with oxygen in the air, so it has good anti-oxidation property. This can prevent the formation of oxides such as copper oxide on the surface of the wire core, and avoid the increase of resistance and decrease of conductivity due to oxidation. Even under long-term use and different environmental conditions, the spring power cord with oxygen-free copper core can still maintain stable electrical performance and ensure the reliable operation of the equipment.

Anti-electromagnetic interference: Oxygen-free copper has a certain shielding effect, which can effectively reduce the influence of external electromagnetic interference on the power line transmission signal, and also prevent the electromagnetic radiation generated by the power line itself from interfering with surrounding equipment. This is very important for some electronic equipment with high requirements for electromagnetic compatibility, such as computers, communication equipment, etc., which can ensure the normal operation of the equipment and avoid signal interference and data transmission errors.
